Re: RAMPS for Due!
For what it is worth, I'm happily using the later Geetech board (the one with actual fuses). In my case, I'm using 5 volt VCC, and I had to hack the board slightly to make the hot end thermistor work...

Hey guys! So I'm building a DIY Taz, and I'm trying to figure out how to properly hookup the heatbed to the RAMPS 1.4 board. The heatbed is 12"x12" and 12V, and it will be connected to a regular RAMPS...

I don't think that's reasonable, a normal MK2 printer uses only 16A going full-tilt... 20A should be enough. It probably needs to be thermally isolated beneath, to conserve heat, but we tried that and...

What kind of bed is that? Try using a multimeter to check its resistance. Only after that you can figure out how much current it will draw when supplied with 12v. For example if it has 0.9 ohms, it...

Thanks for the reply! This is the board I ordered: [www.ebay.com] I haven't received it yet, but I'll measure the resistance when I get it. But the add says I'll probably need a relay (and I've read...

The mosfet itself probably can handle that, but the ramps has a series PTC fuse that is set ok up to 11A, you need to avoid that fuse. Also the pcb tracks are sort of small and long, especially the...

If you want to use the mosfet in place and reinforce the tracks, i attached a picture which shows 2 tracks to reinforce to the mosfet terminals. It should be done with a solid core copper wire,...
